It is assumed that the alternation of the stresses in the nanolayered amorphous AlN/BNC coatings is a major factor of their strengthening. First-principles studies of the heterostructures showed that 3C-SiC and B1-AlN layers between B1-TiN layers (TiN / SiC and Ti / AlN system, respectively) are stabilized. An AlN epitaxial layer is unstable in the nanolayered system ZrN/AlN; a bcc-Ti layer is stabilized between the layers of bcc-V. A criterion of the stability of the epitaxial ceramic layers between TiN ones is developed. Coating materials such as NbN and Ti2N were theoretically investigated. Based on the research results and magnetooptical properties of Fe3O4 galvanomagnetic films, and the MeXOY/Fe3O4 and MeXOY/SnO2 film pairs shown that the magnetization of the films increases with the magnetic moment of the rare-earth metal ion Me and currents in contacting layers. The same dependence takes place for Cu/Fe3O4/MeXOY/Fe3O4/Cu nanostructures that consist of similar layers. In these systems, an increase in the spin polarization of conduction electrons in Fe3O4 and tunnel magnetoresistance is observed during their operation at DC and alternating currents.
